How to Fix a very slow Windows 7 installation

Whilst trying to install Windows 7 via USB Key Disk (find out how to install Windows 7 from USB Key Disk) I came across an odd and frustrating problem – once Windows 7 had booted into its setup routine, it went really, really, really slow. By slow, I mean minutes in between changing screen prompts.

Thinking the issue was USB based, I burned Windows 7 to a DVD and tried booting from that. Same issue, sllllllow installation.

The machine in question was based on a Asus P5B Motherboard, and so I went into the BIOS to do some digging around.

Asus P5B BIOS ScreenshotI noticed that within the BIOS, the option for a 1.44mb 3.5” Floppy Disk Drive was turned on – despite the fact the machine didn’t have a FDD.

I disabled the FDD, rebooted Windows 7 from USB Key Disk, and the installation started to fly by. 15 minutes later, I was running Windows 7.

I’ve seen this same sort of issue with Windows Vista installations as well, so the lesson here is – make sure you’ve turned off Floppy Disk Drives in the BIOS before attempting a Vista or Windows 7 installation.

    ASUS P6T V2 owner here - thanks a ton. It's pretty rare that you come across a piece of advice that makes such a night-and-day difference. This prevented me from having to delay selling my old PC, so thanks!

    Krishna -- my pleasure! I'm glad to have been of help. As for your 500gb HDD problem, firstly I'd check the drive model number via a Google search to check it is definitely 500GB and not a 300GB model. Secondly, I'd delete all the existing partitions and format the drive from scratch. Let us know how you get on!

    Hi, Raju. Be aware that Windows 7 has already gone past the Microsoft End of Mainstream Support date (Jan 13, 2015). See If you're still having issues installing Windows 7, it may be worth exploring installing Windows 10.
